The "FG" and "BG" parameters let you assign different values to strokes made with and .
It is often useful to use as "erase". For example, if Paint method is "Replace", you might set FG value to
50and BG value to
0, so sets the height and clears it.
Or if Paint method is "Add", you might set FG value to
50and BG value to
-50, so adds height and removes it.
Updating the display can be slow with high-resolution volumes, and the stroke may drop points. You may need to draw slowly to capture finely detailed strokes.
The node caches the incoming volumes for speed. If you change something upstream, you need to click Recache strokes to re-apply the existing strokes to the changed volumes, otherwise this node’s display won’t reflect the upstream changes.
Click to clear all strokes in this node.
Re-cache the input volumes and re-apply any existing strokes.
The name of the layer to paint into, for example
Tint by Current Layer
Apply an implicit heightfield visualization to change the tint layer to tint white-to-red the current stroke layer.
How to combine this mask with any existing mask in the input.
Clear the existing mask and replace it with the new mask.
Add the values in this mask to any existing mask.
Subtract the values in this mask from any existing mask.
Set the mask values to the difference between the old mask and this mask.
Multiply the values of the old mask by the values in this mask. This might be useful to "scale" existing values while leaving empty areas alone.
Set the mask values to the maximum of the old mask and this mask.
Set the mask values to the minimum of the old mask and this mask.
Blend the old mask and this mask by a certain amount.
The maximum value for strokes made with . For masks this would usually be
1, or for the height layer the highest peak you want to be able to make or the most you want to be able to add/subtract/etc at once. Pressure sensitive input can scale this value down.
The maximum value for strokes made with .
A scale on the FG value. This can be useful to drag into the viewport as a HUD slider so you can adjust the strength of each stroke on the fly, especially if you don’t have a pressure sensitive input device.
The maximum radius of strokes. Pressure sensitive input can scale this value down.
The plane onto which your drawing is projected. There are basically two useful options: the plane corresponding to the orientation of the volume (ZX by default) so you can draw looking "down" at the ground, or "Geometry" so you can draw onto the visualized terrain.
Project onto the given plane. Choose the plane that corresponds to your volume’s orientation.
This option is copied from the underlying Stroke SOP and is not useful for height fields.
Finds the geometry under the mouse as you draw and maps it onto the corresponding coordinates on the ground plane.
The sampling rate of the brush stroke. Higher values can capture more detail but use more memory and are slower to display.
Keep strokes active and do not cache. ???
